Notes. The table lists: (Col. 2) the star formation rate and (Col. 3) the specific star formation rate per unit luminosity; (Cols. 4 and 5) the metallicity obtained with the N2 and the O3N2 indicators; (Col. 6) the ionisation parameter log U estimated using the [S ii] lines and the formulation given in Díaz et al. (2000), and (Col. 7) the estimate of the extinction E(B−V).
